Question

Name the physical quantities to be kept constant for ohm's law to be true

Answer 1

Temperature, length and area of cross section

Answer 2

The connection between voltage, current, and resistance is illustrated by Ohm's law. Ohm's laws declare that the current through any two points of the conductor is directly proportional to the potential difference applied over the conductor, given the physical conditions i.e. temperature, etc. do not change and remains constant.
